Question

How address bus and data bus are separated in 8085 microprocessor ?​

Answer 1

Answer:

multiplexed with each other

Explanation:

The data bus and the low order address bus on the 8085 microprocessor are multiplexed with each other. This allows 8 pins to be used where 16 would normally be required. The hardware interface is required to demultiplex the bus by latching the low order address in the first T cycle, on the falling edge of ALE.

Answer 2

Answer: 8085 Microprocessor processes 8 bits at a time. Hence, the data bus is of 8 bits i. e. 8 parallel lines to carry each bit of the 8 bits of data. For the 16-bit address bus, 16 pins are needed. For the 8-bit data bus, another eight pins are needed.
